Abstract
Globalisation is associated with long periods of sustained economic growth and credit expansion, whereas major recessions tend to lead to falling trade and protectionism. I investigate this, using a model where an important component of trade is search by firms trying out new trade partners. To model this, I set up a schematic model of upstream-downstream matching between firms, where match quality determines profits. Prior to globalisation, Northern upstream and downstream firms work together, to avoid trade costs. As trade is liberalised, new North-South matches begin to develop, but at first these are footloose (since many are experimental in nature), and can be driven out rapidly if there is a demand crisis.
The presence of a highly elastic, searching element of trade, during periods of global liberalisation and fast growth means that countries cannot gain terms-of-trade advantage from protection. By contrast, if a prolonged recession drives out searching firms, the remaining trade is relatively price-inelastic, and beggar-thy-neighbour tariffs become attractive.
Such observations are consistent with the rapid and damaging switch to protectionism after the 1929 Stock Market Crash, and emphasise the need for continued multilateral commitment to trade liberalisation, in the aftermath of the 2008 Great Trade Recession.

Ishii and Yi (1997) use fixed costs of vertical specialization to explain the high observed income elasticities of trade—which they argue cannot plausibly reconciled with more orthodox models.

In terms of a macroeconomic model, market search has elements of capital formation, and so it should be no surprise that it has many of the characteristics of investment demand—in terms of cyclical sensitivity.

This setup is derived from Salop’s circular cylinder, and is standard in firm-level matching models. Note that Grossman and Helpman’s (2002) model is similar, except that firms know with certainty the location of potential partners, and always match with the nearest.
